1:early_suspend
late_resume添加log 在earlysuspend.c中 static int debug_mask = DEBUG_USER_STATE; -> static int debug_mask = DEBUG_USER_STATE | DEBUG_SUSPEND | DEBUG_VERBOSE; 就可以打印出對(duì)應(yīng)的設(shè)備。 2:resume suspend debug 在platform.c（driver/base）中添加log，打印相應(yīng)設(shè)備： int platform_pm_suspend(struct device *dev) { struct device_driver *drv = dev->driver; int ret = 0; if (!drv) return 0; if (drv->pm) { if (drv->pm->suspend) ret = drv->pm->suspend(dev); +printk("%s called name = %s\n",__func__,drv->name); } else { ret = platform_legacy_suspend(dev, PMSG_SUSPEND); } return ret; } int platform_pm_resume(struct device *dev) { struct device_driver *drv = dev->driver; int ret = 0; if (!drv) return 0; if (drv->pm) { if (drv->pm->resume) ret = drv->pm->resume(dev); +printk("%s called name = %s\n",__func__,drv->name); } else { ret = platform_legacy_resume(dev); } return ret; } log: <6>[ 53.643766] request_suspend_state: sleep (0->3) at 53636581667 (1970-01-02 08:21:01.108440452 UTC) <6>[ 53.651854] early_suspend: call handlers <6>[ 53.655669] early_suspend: calling ft5x06_ts_early_suspend <6>[ 53.663818] early_suspend: calling stop_drawing_early_suspend <6>[ 53.682527] early_suspend: calling kgsl_early_suspend_driver <6>[ 53.687166] early_suspend: calling msmfb_early_suspend <6>[ 53.748298] msm_hsic_host msm_hsic_host: HSIC-USB exited from low power mode <3>[ 53.757271] mdp4_mixer_blend_setup: Error: no bg_pipe at mixer=0 <4>[ 53.762276] mipi_sharp_lcd_off <6>[ 53.921562] mipi_dsi_lms_panel_power: on=0 <6>[ 53.926171] early_suspend: calling msmfb_early_suspend <6>[ 53.930749] early_suspend: calling mdp_early_suspend <3>[ 53.935235] dtv_pipe is not configured yet <6>[ 53.951716] early_suspend: calling msmsdcc_early_suspend <6>[ 53.955989] early_suspend: calling msmsdcc_early_suspend <6>[ 53.961819] PM: Syncing filesystems... <6>[ 53.966061] sync done. <6>[ 53.967404] active wake lock msm_hsic_host <6>[ 53.971463] active wake lock PowerManagerService <6>[ 55.280024] msm_hsic_host msm_hsic_host: HSIC-USB in low power mode <6>[ 55.425301] msm_hsic_host msm_hsic_host: HSIC-USB exited from low power mode <6>[ 57.269342] msm_hsic_host msm_hsic_host: HSIC-USB in low power mode <6>[ 58.209522] suspend: enter suspend <6>[ 58.211963] PM: suspend entry 1970-01-02 08:21:05.676635122 UTC <6>[ 58.217945] PM: Syncing filesystems... <6>[ 58.225911] sync done. <6>[ 58.227468] PM: Syncing filesystems... <6>[ 58.232992] sync done. <4>[ 58.234640] Freezing user space processes ...
